Is mixed flash memory of mobile phone true or false? I’ll teach you how to check the flash memory model of your mobile phone

Recently, it is rumored on the Internet that a mobile phone uses flash memory mixed with UFS 3.0 flash memory and UFS 3.1 flash memory on the same model of machine. If you buy a mobile phone with different capacities, the flash memory protocol is different. Judging from this description, this practice is quite inhumane, consumers buy mobile phones is tantamount to lottery. < / P > < p > but is this true? Many friends have only heard about it, but they don’t know how to verify it. Today, I would like to share with you some methods. < / P > < p > this method is applicable to some ROMs. For example, some versions of MIUI, emui and other ROMs can be used. In the dial-up interface, enter “* ා *” and the system will start to generate a debug report. Wait for the debug report to be generated. The whole process should be less than one minute. < / P > < p > this debug report contains many files. Take MIUI as an example. These files are stored in the “MIUI debug” internal storage of the phone_ Log “directory. Open this directory, find the “bugreport date time” file name format zip package, and open the zip package. < / P > < p > in this zip package, there is another zip package with the file name “bugreport device name Android version date time”. < / P > < p > in this TXT file, search for the string “FFU”, and you can easily find the information about the flash memory model. For example, the mobile phone in my hand has a flash memory model of “klucg4j1ed-b0c1”, and the manufacturer is Samsung. < / P > < p > this method is suitable for most Android phones. First of all, you need to open the Android Developer option. In the system information interface of the settings menu, click “version number” to open it. < / P > < p > then, the “developer mode” option is added to the setting interface, which is usually located under “system”. In the developer option, you can see the function of “error report”. After clicking, select generate report. < / P > < p > after waiting for a period of time, the message “error report obtained” will pop up in the system notification bar. Click on it, see the warning message, and save it to the system directory. The next “bug report” method is called “bug report” with the name of “bug report”. In this zip package, find the txt file with the same name, and then search for “FFU” to find the flash model. < / P > < p > however, it should also be noted that some manufacturers do not write the relevant information of flash memory into bugeport by default, or the search keywords are different, which requires you to try it in person. < / P > < p > Android system is based on the Linux kernel, so if you want to confirm some information about the Android machine, you can also use the terminals commonly used in Linux. < / P > < p > however, this method can not be used by any machine. Some manufacturers have blocked the call of relevant information. Even if the command is input, it will not return any information, so the information of flash memory model can not be seen. < / P > < p > this time, some friends bought the 256g capacity model of a mobile phone. Because the flash memory score was slightly lower, they were suspected to be UFS 3.0, which was not consistent with the UFS 3.1 publicized. It is understood that the corresponding flash model is “sdinfdk4-256g”. We will take it as an example to identify what the flash memory specification is. < / P > < p > from the file, it is easy to find the corresponding specification of “sdinfdk4-256g”. Visible this is UFS 3.1 flash memory, propaganda is not wrong. < / P > < p > as for the performance difference between 128G version and flash memory version, the performance of flash memory is not only related to the protocol, but also an important determinant – just like the SSD of pci4.0, the performance of different models is also different. < / P > < p > in general, as an important part of mobile phone, flash memory really determines the experience of mobile phone to a large extent. If you have doubts about the flash signal, you might as well try the above method, I believe it can help everyone. Privacy Policy
